Primarily focused on Java SE software development, I also have experience in web development and server technologies. I am always happy to take on a challenge. Certified Vaadin 7 and Vaadin 8 developer.

In the summer of 2011 I developed small data transformation middle-ware applications with Swing graphical user interfaces. The solution was a tool that transformed exported Ebay auction data into the formats required by the customer's billing and shipping systems. This software saves the customer many man-hours of work per day.
Since then I have worked on several projects of various sizes and scope. From the end of 2011 until spring 2014. At the same time I completed my studies as a Business Information Manager (bachelor's degree). In 2014 I was hired by the Deutsche Börse as a full time software developer and have worked primarily with Java and related server and web technologies since.

Near the end of 2014 I was asked to develop a prototype web application that was based on an existing Java Swing trading GUI (finance sector). After the successful completion of this project I was involved in a number of prototype and proof-of-concept development projects using GWT.
Lately I have been involved in some high-complexity large-scale projects that use Vaadin. By combining my knowledge of Java and web development (I have worked on many websites in the past) I was able to learn a lot about Vaadin and it has become my go-to framework for Java web applications.
I am a certified Vaadin 7 and Vaadin 8 developer.

By working for the Deutsche Börse since the end of 2011 as a student freelancer and since spring 2014 as a full time employee, I have amassed a lot of knowledge about stock market trading systems and applications. Naturally, my emphasis lies with the systems run by the Deutsche Börse, but the concepts of financial applications are widely applicable within the sector.

Being interested in all things software, I have naturally had a lot of exposure to the Microsoft Office suite. I have also used advanced features in a professional environment. One example is helping the controlling department of a company completely overhaul their Excel sheets and Access databases. I also frequently work with smaller firms and help maintain their Access databases in the face over ever-increasing requirements.

Timothy is a great, smart and friendly. He helped me through my problem very well. Excellent in explaining and very clear. I will always be thankful for him. I strongly recommend him. The final word, thanks Timothy.
